Motivation

• Provide a concise, actionable list of small fixes (documentation typos/links, a defensive bug fix, a docs/metadata inconsistency, and a test improvement) discovered during a quick codebase review so maintainers can take targeted follow-ups.

Description

• Added docs/issues/2026-02-17-codebase-task-vorschlaege.md which enumerates four concrete tasks: correct broken internal links in docs/8_development/1_overview.md, defensively handle empty YAML in cli/aitbc_cli/commands/config.py export, reconcile the Python minimum version between docs and pyproject.toml, and fix duplicate test_environments definitions in tests/cli/test_config.py.

Testing

• Ran pytest -q tests/cli/test_config.py, which failed during collection with ModuleNotFoundError: No module named 'aitbc_cli'; no code tests were added because this is a documentation/triage change.
